Kristin Cavallari Recalls Her Best And Worst 'Hills' Moments

'I think my biggest thing was the first episode ... I really came in with a bang,' she tells MTV News of season-five appearance.

Kristin Cavallari entered "The Hills" like a human storm during one of the show's most pivotal episodes. Just as Speidi were finally set to tie the knot for real (and Lauren Conrad to say a final farewell), Cavallari walked into the church and the MTV reality series hasn't been the same since.

Not only has the blond star managed, in just under two seasons, to make moves on both Justin Bobby and her ex Brody Jenner, but she also stirred up trouble with Justin's on-again, off-again GF Audrina Patridge, as well as with Brody's ladies Jayde and McKaela. (Kristin even had a little hookup with gal pal Stacie.) So between falling in love and making enemies, we wondered what stood out the most to Kristin. MTV News asked the show's leading lady to give us her most memorable [url id=""]"Hills"[/url] moment.

"Gosh, top moment ... I think I had a couple," she told us, recalling her rooftop fight with Audrina over Justin during the premiere episode of the second half of season five. "I think my biggest thing was the first episode where I really came in with a bang," she laughed. "And it was like, 'All right, clearly I'm back.' "

These days, everything's fine between Kristin and Audrina; the two ladies managed to kiss and make up, so to speak. However, one lady Cavallari said she wishes she'd never actually kissed is her bartender pal.

"I think that's sort of my I-wish-I-didn't moment was when I made out with Stacie in Vegas," she explained. "That was one episode I had to call my dad and say, 'Dad, sorry — this is going to be your least favorite episode.' "

It was a moment that not only surprised viewers at home, but her father too. "He was like, 'Oh, great,' and then when he called me — sometimes he'll call me after every episode just to talk about it — he didn't say one word about the episode. I don't know if that's a good thing or a bad thing. ... It's probably a bad thing," she laughed.

Despite that one regret, Cavallari admitted she's never been shy about her bad-girl ways. In fact, she always fully embraces them, right through to "The Hills" series finale on Tuesday.

"I think it's funny," she laughed about her carefree attitude when it comes to boys and, well, girls. "Honestly, I think it's fun to play the bad girl, and no one remembers the nice girl, you know?"
